Error after Installing .Net runtime 1.0 patch 3

Hi ALL,

I have installed the .Net runtime 1.0 patch 3 over a SAP portal SP12 (on WIN 2003) and it was done successfully.

But when I tried to restart the service of the runtime 1.0 patch 3 I got an error message saying that the connection was broken and the service disappeared from the services list.

On the event log I got the error message : "

Product: SAP Portal Runtime 1.0 Patch 3 for Microsoft .NET -- Error 1923.Service SAP NetWeaver Portal Runtime 1.0 Patch 3 for Microsoft .NET Server00 (SAP NetWeaver Portal Runtime 1.0 Patch 3 for Microsoft .NET Server00) could not be installed. Verify that you have sufficient privileges to install system services."

When I entered the portal I got the following error message :

Error classification : class java.lang.ClassCastException

Stack Trace :
